Last week HPE published a bullettin. HPE SSD disks running prior to HPD8 firmware may have failure after 32.768 hours (3 years, 270 days, 8 hours), so you can lost your data on these disks. Therefore HPE recommends apply HPD8 firmware to these disks which are listed in bullettin. You can find details and affected disk models in below link.
If you are using VMware VSAN, please check certified firmware level of VSAN disks which are affected this failure.
